Key facts
FSWX signal and spectrum analyzer
In today’s fast-paced technological landscape, having a reliable and efficient signal analysis solution that can transcend the limits and overcome the limitations of traditional measurement methods is crucial. The cutting-edge multipath FSWX architecture brings a new level of performance and precision to signal analysis. By applying preselection, suppressing inherent noise and spurious signals and minimizing unwanted artifacts, the FSWX ensures that the true characteristics of the signal under test are accurately captured and analyzed.
Phase coherent capture at the same or at different frequencies
The ability to capture wideband, modulated phase coherent signals at the same or different frequencies opens up new measurement scenarios. The FSWX is the first multichannel signal and spectrum analyzer to do so.
Multiple input ports allow for phase coherent capture of multiple signals. This example shows a comparison of the amplitude and phase of two phased array antenna ports as well as the group delay.
Measure noise level down to the physical limit
The FSWX is the first signal and spectrum analyzer with cross-correlation. Cross-correlation cancels the inherent noise of the analyzer and gives a clear view on the device under test. With cross-correlation, you can push the noise level down to the physical limit for higher dynamic range in noise, phase noise and EVM measurements or spur searches. Benefits include:
Cross-correlation eliminates the analyzer’s inherent noise and provides an unobstructed view of the signal. Without cross-correlation, the spectrum re-growth of the amplifier under test would not be visible in this example.
Up to 8 GHz analysis bandwidth
The FSWX has been designed as a wide bandwidth instrument. Each analog signal path is terminated by high-resolution, high-speed ADCs providing 8 GHz of analysis bandwidth. This concept includes:
Default filter banks with optional YIG preselector
The FSWX features filter banks with independent highpass and lowpass filters across the whole instrument frequency range. Benefits of filter banks vs swept preselection filters include:
